+## Add a date field to a PDF form
+
+This section explains how to add a date text box field to a PDF form using the Syncfusion PDF library. The field is initialized with a sample date and uses JavaScript-based formatting to enforce the date format, validate input, and automatically format user entries.
+
+The following code example illustrates how to add a date field to a PDF form.
